WebIt is composed mainly of iron (Fe) and nickel (Ni) and hence it is also called as NIFE. The core constitutes nearly 15% of earth’s volume and 32.5% of earth’s mass. The core is the densest layer of the earth with its density ranges between 9.5-14.5g/cm3. The Core consists of two sub-layers: the inner core and the outer core. WebThe outer core is the only liquid layer found within Earth. It starts at 2,890 km (1,795 mi) depth and extends to 5,150 km (3,200 mi). Inge Lehmann, a Danish geophysicist, in 1936, was the first to prove that there was an inner core that was solid within the liquid outer core based on analyzing seismic data. The solid inner core is about 1,220 ...
